Myiinvention relates toan improvement in aprocessof impregnating itxfilbllO with a substantially permanent fragrance and the product produced thereby as will be more 1 fully hereinafter pointed out.

a In the present age of the very general use of face powders,the powder puff has become an; article of every day use by the majority of women.

Such powder puffsare usedso frequently that many women carry them with them at all times. It therefore has become important that the powder puff itself shall carry a pleasing odor orfragrance so that its use 'will not only notbe offensive, but will be pleasing to. those around whomthe puff is used. 7 A puff carrying such a desirable fragrance also will add to the desirable fragrance of the powder asused, thereby making the use of the powder more effective.

Because of the difiiculty in securing a fragrance which is substantially permanent no such powder puff nor the fabric for making the same has been produced heretofore.

My process is adapted to solve this problem in that it prepares a .pile fabric or the like with a substantially permanent back coating of required fragrance together with a pile .or face fabric impregnation of a more volatile fragrance blending with the fragrance of the back coating without interfering with. the effectiveness of the face or pile, whereby a powder puff or other article may be made of this material so treated withthe assurance that it will sustain the desired pleasing fragrance as long as the same may be useful. c

There are many fragrant gums which.

. may be used toform'a compound solution suitable for coating the back of a fabric but in order that we-may have these definitely before us the following fragrant gums, balsams and natural 1 and synthetic derivatives 1 are named, all of which are suitable forthe purpose and all ofiwhich have ana-tural fragrance and which, in combination, will form the desired substantially permanent fragrance for our fabric. Among others we name: benzoin, labdanum, styrax, tolu, balsam peru, civet, tonkin musk, ambrette, oli' :banum, guaj'aic woodfconcrete form), oris root (concrete form) and phenyl acetlc acid. As these are all fragrant gums, balsam's or natural or synthetic derivatives, a composition of all or any of them, put into so Ap ilication filed September 1, 1925. Serial 1%. 53,957;

lar practice, must be made from a pile of fabric, it is necessary in handling-such 'fab-, no to keep. the pile free from any pressing or rubblng', as this tends tomat the pile and thereby spoilthe desired effect and function of the pile as it is this soft, flexible. and brush-like pile which-picks up the powder and applies it to 'theface'so efficiently. 7

Therefore, in order to dry the solution of the fragrant; gum compound, it is necessary;

to make use of well known. drying frames, which are commonly used nthe handling of pile fabrics whereby the. fabric-is held. on

the selvage edges in such a manner that nothing will contactwiththe face or pile of the fabric; These frames or racks/are known as pin hook steel. racks being c0mmonly used in the handling of pile fabrics to prevent the crushing of the pile. r

111 order to effect the drying of the coating on the back of thefabric, the coated fabric mounted on such pinhook steelracks asdescribed,,can be placed in a steam heated vacuum retort which may be hermetically sealed and a vacuum created in said retort by means of a pump, following which:

the steam can be turned on to the jacketed retort permittingthe. fabric to remain in this vacuum under heat forha sufficient length of time to insurefthoroughdrying of the back coating and the elimination-of'any other moisture in. thezfabric. Any other well known means. which will, effect. the thorough drying of the back coating will answer the requirements of the process. 7

Making use of the retort and the vacuum therein, the fabric may be further impregnated with a volatile fragrant material combined with some of the aforementioned fragrant solution which Will particularly impregnate the pile or face of the fabric by supplying an odorant having a volatile fras grance combined with the substantially permanent fragrance to the vacuum retort thereby insuring thorough impregnation of the resillue ojfi the {fabric without the loss of any substantial amount of odorant used. Such an odorant solution of volatile -fragrance combined witlrthe substantially permanent fragrant solution ma also be fiPlM Qd B1101 till? :aflg :VQI epi m the fab1'ic in any Well known manner without tl e use of any vacuum retort while the fabric is still warm fromits drying whereby it -will readily absorb such odorant in a more complete. .manner than would-be possible :if spmyed on :to ;the fabric when the Eta-brie is cold. eS nch impregnating or spraying of the face. or [pile nvill @not .in any may change :the
